Bill Cockyne put me onto an interesting cnet article on mouse gestures, in which a combination of mouse movements– say, right-click and hold, move left, up, then release– trigger a command like “save” or “print.” It’s a great example of how popular use of the mouse is growing more powerful; gestural mousing has been around in the lab for a while, and has been used by computer professionals, but hasn’t been part of the universe of popular computer use.
